No you just have to sideload the los zip and afterwards the gapps zip, that's itWhen updating to 19.1, do I need to reset the system or cache partition before flashing the new package and gapps? It is not mentioned in the tutorial so I would expect not.
I guess the new package might just completely override the old system partition, but why then does flashing the gapps not completely override the new package?
Am I supposed to flash the same GApps package as I flashed on 18.1 (I think MindTheGApps) or can I flash whatever GApps package I like (e.g. NikGApps Core) on upgrading official 18.1 to official 19.1?
I think you can but I'm not 100% sure, I had Open GApps with LOS 18 and dirty flashed LOS 19.1 with MindTheGApps without a problem.
Successfully upgraded with TWRP 3.6.1, Reinstalled Magisk and patched boot.img, SafetyNet passes
From 18, I upgraded TWRP to the latest compatible version using the TWRP app, then wiped system (kept data intact), and installed Lineage 19 + MindTheGapps. All worked perfectly, except that TWRP can't decrypt data any more, but that doesn't affect OTA updates, and it should come with a new version eventually.i'm on the final auto upgrade version of lineage 18, and my trusty dumpling is equipped with twrp 3.5.1_9-0
is it possible to either dirty flash the next iteration using twrp, or even to delete the data and start anew with the lineage 19 zip from there?
is that a crazy idea? should i move on to lineage recovery (which is a mystery to me)?
i confess i am not keen to adopt lineage recovery because i have used twrp since days of yore, and feel at ease with the set up
thanks for some knowledgeable comments
